First post, first tutorial not going so well.
I've selected the Lathe Solid tool and am attempting to select curves to lathe. The first selection gives an apparent error message, "Curves not Planar" and won't allow me to select the line. It's a horizontal straight line; pretty straightforward. What's going on? I'm feeling rather foolish here, unable to perform even the simplest task... Sheesh.
I've never used any CAD program, but have done some simple 3D modeling.
Any ideas will be greatly appreciated. Thanks,
